Assumption that all questions are wright we will get (75*4=300)
Getting marks 125 then these marks are subtracted from 300 then(300–125=175)
If one question wrong we will loose (5 marks)because every wrong answer penality 1 mark and we didn't get 4 marks also if question wrong that's why we loose (5 marks)
Then getting marks are divided by 5 (175/5=35)
Last step total questions -wrong answer questions. (75–35=40)
So that answer will be 40
